This test dates from the time when llvm-gcc had problems if two types were
named the same, so it had to qualify type names according to the enclosing
scope to ensure uniqueness.  This is no longer needed for correctness (though
it may be helpful when reading the IR), so this test has lost its importance.
Zap it because dragonegg will never be able to produce the qualified type name
since modern gcc zaps language specific info (such as whether a type is nested
inside another - needed to get X::Y here) before dragonegg is reached.

Implement the first half of LiveDebugVariables.

Scan the MachineFunction for DBG_VALUE instructions, and replace them with a
data structure similar to LiveIntervals. The live range of a DBG_VALUE is
determined by propagating it down the dominator tree until a new DBG_VALUE is
found. When a DBG_VALUE lives in a register, its live range is confined to the
live range of the register's value.

LiveDebugVariables runs before coalescing, so DBG_VALUEs are not artificially
extended when registers are joined.

The missing half will recreate DBG_VALUE instructions from the intervals when
register allocation is complete.

The pass is disabled by default. It can be enabled with the temporary command
line option -live-debug-variables.

I don't think it makes any sense to assert that the target supports SSE3 here.
The user (i.e. whoever generated a call to the intrinsic in the first place) is
essentially asking for a particular instruction to be placed in the assembler.
If that instruction won't execute on the target machine, that's their problem
not ours.  Two buildbots with processors that don't support SSE3 were barfing

Remove "comparison of integers of different signs" warning by making the
variable unsigned.

Support/PathV2: Remove is_valid. It was only added because Path had it, but
apparently it is unused.

Delete Path::appendSuffix's return value; it wasn't used anywhere, which
is fine since isn't really necessary to check isValid there anyway.

ARM/MC/ELF relocation "hello world" for movw/movt.
Lifted adjustFixupValue() from Darwin for sharing w ELF.
Test added
TODO:

  Possibly share more code with Darwin?
  Lots more relocations...

fix a bozo bug I introduced in r119930, causing a miscompile of
20040709-1.c from the gcc testsuite.  I was using the size of a
pointer instead of the pointee.  This fixes rdar://8713376

Comment typo.

git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@120504 91177308-0d34-0410-b5e6-96231b3b80d8

Enable sibling call optimization of libcalls which are expanded during
legalization time. Since at legalization time there is no mapping from
SDNode back to the corresponding LLVM instruction and the return
SDNode is target specific, this requires a target hook to check for
eligibility. Only x86 and ARM support this form of sibcall optimization
right now.
